Before entering into quantity production, an acceptable first article sample of 72 cartridges shall be prepared using the same procedures and methods proposed for the produ
31、ction lot. Sixty-six of these cartridges shall be expended in the tests listed herein and six shall be retained for investigative purposes. A First Article sample acceptable for functional and environmental testing shall be defined as a sample which has met the requirements of paragraphs 3.2 through
32、 3.5 of this specification. The contractor shall deliver the cartridges to the activity designated by the contracting agency for tests. First Article sample inspection shall consist of the following tests: leak (72), temperature and humidity cycling (18), vibration (12) shock (12), 65 F 5 F (12), an
33、d 200 F 5 F (12). The numbers in parentheses denote the number of cartridges allotted for each test. All tests are done as prescribed in Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-32194B (OS) 5 MIL-D-21625 except vibration which is presc
34、ribed in 4.9 herein. The cartridges shall be fired as described in 4.10 and shall meet the functional requirements referenced in 3.6. Any quantity production prior to notification by the contracting agency of First Article sample acceptability shall be at the contractors risk. The First Article cart
35、ridges will not be applied as part of the quantity specified for delivery by the contract. 4.4 Cartridges visual inspection. Examine all cartridges and reject those with inadequate or illegible descriptive markings or serial numbers, color coding, dents, deep scratches, or other defects which may pr
36、event proper installation or function. 4.5 Cartridge leakage. Each cartridge in the ballistic sample shall be leak tested in a dry gas leak tester. Cartridges which exhibit a leak rate in excess of 1 x 10-5cc/sec of air at a pressure differential of one atmosphere 0.1 atmosphere shall be considered
37、defective. If one or more cartridges of the ballistic sample leak, then a leak test of each cartridge in the production lot shall be required. If a 100 Percent leak test of the lot is required, it shall be at the expense of the contractor. Cartridges which exhibit a leak rate in excess of that speci
38、fied above shall be rejected and destroyed. 4.6 Radiographic examination. All cartridges shall be identified with serial numbers prior to radiographic examination. The cartridges shall be arranged on trays or boards in consecutive numerical order, and each radiograph shall carry a permanent identifi
39、cation of the cartridges displayed thereon. The cartridges shall be positioned to give the most revealing cross-section of the cartridge. The radiograph identification shall include the complete lot number, as stamped on the cartridges, and the span of serial numbers displayed. Discontinuities in se
40、rial numbers shall be identified on the radiographic plate. Defective cartridges found by the vendor shall be clearly identified on the radiographic plate and those defective shall be removed from the production lot. Radiographs or copies of the entire production lot shall accompany the ballistic sa
41、mple to the activity conducting the production lot acceptance test. (see 5.1). 4.6.1 X-ray examination. Each cartridge shall be x-rayed in accordance with ASTM E1742, to confirm the presence and proper assembly of all parts. Any observable imperfections in assembly shall be cause for cartridge rejec
42、tion. 4.6.2 N-ray examination. Each cartridge shall be n-rayed to confirm the presence of the propellant, non-metal parts, no foreign hydrogenous materials and the proper assembly of pyrotechnic/non-metallic materials. Any observable imperfection shall be cause for rejection. 4.7 Demagnetization. Ea
43、ch cartridge shall be moved past a pilots standby compass face (in accordance with SAE AS5604) by placing the cartridge six inches from the compass face, in a north-south horizontal position with the compass set in an east-west heading. The cartridge and the compass shall be placed at the same heigh
44、t from the floor. The cartridges shall be moved past the compass face in a longitudinal direction for its entire length, rotated 90 degrees in the horizontal position about its longitudinal axis, and moved back past the compass face. This procedure shall be repeated for each 90 degrees of the cartri
45、dge. 4.8 Electrical bonding resistance. Each cartridge shall be tested using a four point probe milliohmmeter in accordance with MIL-STD-464. The electrical bonding resistance shall be measured between the thread of the SMDC inlet port and the thread at the outlet end of the cartridge. 4.9 Vibration
